POISON-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 177,119, dated June 14, 1892.

Application filed May 4,1891. Serial No. 391,580. (No model.)

To all whom it may concern.-

Be it known thatI, HARRY .I. HILL, residing at Perrys Mills, in the county of Clinton and State of New York, have invented certain new and useful Improvements in Machines for sprinkling Poison upon Plants, of which the following is a specification.

This invention relates particularly to a de vice for sprinkling powdered poison upon plants, the poison being carried by foraminous cylinders, which are revolved as they are transported.

The object of my invention is to provide a device of this character that shall be exceedingly light and simple in construction, easily adjusted to suit various-sized plants, and thoroughly efficient in operation.

\Vith these objects in view my invention consists of a vertically-adjustable platform supported above the beams or main frame, a crank-shaft journaled upon said platform and carrying the distributirig-cylinders, the pitman-rods for operating the crank-shaft and the operating-wheel, and intermediate devices for operating the said pitman-rods.

My invention consists, further, in certain details of construction and combination of parts, all of which will be fully described and claimed.

In the drawings forming a part of this specification, Figure l is a perspective view of my improved sprinkler. Fig. 2 is a detail view of the distributing-cylinder and crankshaft. Fig.3 is a front view of the operating wheel-axle and crank-arms. Fig. at is a detail View of the adjustable platform. Fig. 5 is a side View of the operating-wheel. Fig. 6 is a detail view of the adjustable pitman-rod. Fig. 7 is a similar view of the hanger. Fig. 8 shows one of the craulcarms, and Fig. 9 is a sectional view of one of the upright standards.

In constructing my improved device I employ the parallel beams 13' B, the operatingwheel B being journaled between the forward ends of the same upon the axle B, while the rear ends of said beams are shaped to form handles, as clearly shown. A box or receptacle M is attached to the beams near their rear ends for the purpose of storing the various parts of the device when not in use, and between the said box and the operatingwhcel are arranged four upright standards T, said standards being arranged in pairs, each pair being connected with a separate beam, and preferably united at the top bya curved cross-piece. In the drawings I have shown each pair and cross-piece formed integral, though thisis not at all necessary.

The opposing inner faces of each pair of standards are provided with the longitudinal grooves V V, and between the four standards T is arranged a vertically-adjustable platform F, said platform being provided with lugs 19 at its corners, which are adapted to enter the grooves V, whereby the platform can be guided vertically between the said uprights, and the said platform is held in its adjusted position by means of setscrews working through the standard and against the said lug.

The platform F is provided with journalbearings f upon its lower face at the opposite sides of the same, and in said bearings is mounted the doublecranked shaft L. Pendent bearing-plates f are also secured to the upper face of the plates at the same sides as the bearingf, said plates being curved or arched and project laterally outward and downward, and in their apertured lower ends is journaled the said crank shaft L, the cranked portion of the shaft being arranged between the bearings f'andf The distributing-cylinders A are mounted upon the outer ends of said shaft L, which cylinders are secured thereon by means of the set-screws it. These cylinders are formed of foraminous material to allow the powder to sift through the same, and said cylinders are provided with a slatted covering A, composed of a number of slats, any one or number of which can be Withdrawn to regulate the distribution of the poison from the cylinder. The cylinders are also supported by means of a hanger D, said hanger being itself supported centrally from the platform F by means of a postf, and the ends of said hanger are bent down and connected with the ends of the crankshaft L, the said ends turning in the aperturcd ends of hanger, thereby providing three independent bearings for the crank-shaft. The axle of the opmrating-wheel has crankarms B 13 connected therewith at the opposite ends of the same, and attached to said crank-arms are the pitmen-rods H II, the opposite ends of said pitmen-rods' being connected with the cranked portions of the crankshaft, whereby the said shaft, and consequentlythe cylinders, are revolved as the wheel B revolves. The pitmen-rods are formed in section, as shown, the overlapping ends of said sections working through a sleeve S, wherein they are secured at any desired point by means of set-screws s. The axle of the operating-wheel is also provided with a ratchetdisk 0, and the wheel is provided with one by the wheel can be moved backward without operating the crank-shaft and cylinder, but will insure the revolution of the axle when the wheel is moved forward.

In operation the cylinders are filled with the powder by withdrawing one of the slats, and after regulating the slats the powder is distributed by moving the machine forward between the rows of plants, thus sprinkling two rows of plants at the same time. The platform can be easily adjusted to suit anysized plant, and the pitman can also be adjusted to complete the connection between the operating-wheel and crank-shaft, and said crank-shaft is rendered particularly steady by means of the various bearings and the pe culiar arrangement of the same. The hoods protect the cylinders against wind and rain, and when the device is not in use it can be taken apart and the various parts arranged in the box M.

Having thus described my invention, what I claim as new is- 1. The combination, with the beams, of the the hanger supported from the platform, the

adjustable pitmen, the crank-arms, and operating-wheel, substantially as shown and described.

3. The combination, with the beams, of the operating-wheel, the axle whereof is provided and described. or more pawls E, attached to the spokes, where- 4. The combination, with the supporting uprights, of the vertically-adj ustable platform arranged between the same, thejournal-bearings attached to the under side of said platform, the pendent bearing-plates attached jalso to said platform, the crank-shaft journaled in said bearings, the cylinders, the adf-justable sectional pitmen-rods, the crankarms, and operating-wheel, substantially as "shown and described.

5. The combination, with the upright standards, of the vertically-adjustable platform, a post secured to said platform, a hanger supported upon said post, a crank-shaft having 'its ends journaled in the ends of the hanger,

the cylinders mounted upon said shaft, the

adjust-able pitmen-rods connected to said shaft, and the operating devices, arranged substantially as shown and described.

6. The combination, With the crank-shaft, of the cylinders mounted thereon and formed of foraminous material, and the slatted covering surrounding said cylinders, one or more of f the slats of said covering-slats being adapted to be Withdrawn, substantially as and for the purpose described.

7. The combination, with the crank-shaft,

of the cylinders mounted thereon, the hanger,

and hoods attached to said hanger. and adapted to protect the cylinders, substantially as described.
